NECK-YUKE AND CAP FOR DRAFT-1 0L158.

Specification of Letters Patent.

1 Application fi1edApri118 ,1914. Serial No. 832,795. r

To all whom it may concern:

Be it known that I, BERNARD J. Evans, a citizen of the United. States, residing at St. Elizabeth, in the county of Miller and State of Missouri, have invented new and useful Improvements in Neck-Yokes and Caps for Draft-Poles, of which the following is a specification.

This invention relates to neck yokes and caps for draft poles; and it has for an object to provide means for securely connecting the cap and neck yoke together and for effectively holding the neck yoke against accidental derangement upon the pole.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangemcnt of parts, as will be hereinafter described and claimed.

in the accompanying drawings :Figure 1 is a perspective View of the pole, showing the cap and the neck yoke applied thereto; Fig. 2 is a longitudinal section therethrough; Fig. 3 is a perspective view of the clevis.

The cap 1 is provided preferably with a hollow forward portion 2 and superimposed rearwardlyextending attaching plates 3. The socket portion 2 of the cap receives the forward end. of the pole A, while the extensions 8 of the cap are disposed upon the opposite upper and lower surfaces of the pole and secured thereto through the medium of fastening devices a. The socket portion 2 is closed by a head 5 at a point immediately in advance of the front. end of the pole and as illustrated said cap is provided with an integral forwardly extending boss 6 which has a slot 7 formed therein, which terminates at its inner end in the axial openings 8 in said head 5.

A clevis 9 is disposed immediately in advance of the head 5 of the cap, and is pro vided with a substantially triangular eye 10 and a shank 11. The shank of. the clevis extends through the opening 8 and into an opening 12 in the forward end of the pole A. The inner end of the shank 11 is pointed, as at 13, to facilitate the attachment of the shank with the pole. A vertical rectangular slot 14 in the shank 11 is adapted to partly register with a similar slot 15 in the pole A. A retaining bolt 16 is extended through the socket portion 2 of the cap 1 and through the alined slots 14 and 15, as shown in Fig. 2, so as to cause the adjacent eye defining portion 20 of the eye 10 of the clevis to be held in the slot? in the head of the pole cap. From this construction, it is evident that the clevis is held against accidental. displacement from the pole; that rotation of the clevis is prevented; and that strain upon the fastening bolt 16 of the clevis will be reduced to a minimum.

The neck yoke 21 has clamping plates 22 and 28 thereon at its opposite sides, and as illustrated eye-bolts 2d are extended through the neck yoke and through the clamping plates. The eyes of said bolts are preferably. arranged in close proximity with the eye of the clevis and as illustrated links 25 are employed to connect the eyes of the yoke with the eye o-f'said clevis, whereby the neck yoke is free for the required movement nponthe pole. The extension of the cap is provided with a loop 26, which receives a ring 27.

From. the foregoing description, taken in connection withthe accompanying drawings, the construction and operation of the invention will be readily understood without requiring a. more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any .of the advantages of this invention as claimed.

I claim A pole having a cap secured thereto, a headyclosing one end of the cap and dis posed in advance of the forward end of the pole and provided with a slot therein, a neckyoke, a clevis having a shank extending into the pole and provided with a substantiallytriangular portion fitting in said slot, means connecting the clevis with the neck yoke, and a retaining device extending through the shank of the clevis and through the pole.

In testimony whereof I afliX my signature in presence of two. witnesses.

BERNARD J. EVERS.
